Be carefull with the region and network. I did the upgrade and the phone upgraded to 2.1, But now it doesn’t recognize my service provider. I need to unlock the Network. And I can’t do a rollback. It’s very frustrating.

Hey man, i did all you said to do, but then when i came to file “build.prop” it could not be opened in text editor, because its “read-only” file. What to do? pls tell :)
